I woke up one morning a few months ago to find a text from my older son that had a link to an article about how the previous night was the first time in Major League history that all 15 HOME teams won their game.  My first reaction was "really?"  Baseball is well over 100 years old and in all that time the home team had not won every game of a scheduled day?  Then I realized that they were not talking about every home team winning, they were talking about all 15 home teams winning on a single day.  There have only been 15 home teams (i.e. 30 teams in the league) for a couple of decades.  The article referenced that going back to 1914 something like this had not occurred.  So, I took this to mean that on a night in which EVERY team was playing that all the home teams had not won their game.   This still seemed surprising until I gave it a bit more thought.
